Hi,

We can't do what Hans asks right now, but it may be worthwhile to add a new if statement in some locations to support this (a similar issue is present for the output routine).

If we have

\newif\iftracingfonts

Then maybe we can do

\def\synchronizefont% {\iftracingfonts\else \tracingnone \fi ........ }

or something similar is possible. WDYT?

we can make a new logging system, something \newtoks \everytracingall \newtoks \everytracingnone \appendtoks \tracingonline \plusone \tracingcommands \plusthree \tracingstats \plustwo \tracingpages \plusone \tracingoutput \plusone \tracinglostchars \plustwo \tracingmacros \plustwo \tracingparagraphs\plusone \tracingrestores \plusone \showboxbreadth \maxdimen \showboxdepth \maxdimen \tracinggroups \plusone \tracingifs \plusone \tracingscantokens\plusone \tracingnesting \plusone \tracingassigns \plustwo \to \everytracingall \appendtoks \tracingassigns \zerocount \tracingnesting \zerocount \tracingscantokens\zerocount \tracingifs \zerocount \tracinggroups \zerocount \showboxdepth \plusthree \showboxbreadth \plusfive \tracingrestores \zerocount \tracingparagraphs\zerocount \tracingmacros \zerocount \tracinglostchars \plusone \tracingoutput \zerocount \tracingpages \zerocount \tracingstats \zerocount \tracingcommands \zerocount \tracingonline \zerocount \to \everytracingnone \appendtoks \errorstopmode \to \everytracingall \def\tracingall {\the\everytracingall } \def\tracingnone{\the\everytracingnone} \def\loggingall {\tracingall\tracingonline\zerocount} \newcount\tracingalldepth \let\normaltracingall \tracingall \let\normaltracingnone\tracingnone \let\pushtracingall\donothing \let\poptracingall \donothing \def\tracingless {\def\pushtracingall {\global\advance\tracingalldepth\plusone \ifcase\tracingalldepth\or \normaltracingnone \fi}% \def\poptracingall {\ifcase\tracingalldepth\or \normaltracingall \fi \global\advance\tracingalldepth\minusone}% \normaltracingall} \let\xsynchronizefont\synchronizefont \def\synchronizefont {\pushtracingall \xsynchronizefont \poptracingall} \tracingless test {\em test \bf test} test this is rather efficient (no checking when not enabled) implementing an iftracingfonts can then be done on top of that, for instance \def\synchronizefont {\pushtracingall\tracingfontmode \xsynchronizefont \poptracingall\tracingfontmode} and something \settrue \tracingfontmode needs a bit of thinking because we need to add code all over the place Hans Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
